[PATCH 0/4]Diskdump Update

[Takao Indoh <indou.takao@soft.fujitsu.com>]

Hi,

I update the Diskdump patch for kernel 2.6.6. I fixed some codes 
according to comments from Christoph Hellwig.
http://marc.theaimsgroup.com/?l=linux-kernel&m=108566610109915&w=2

Source code can be downloaded from
	http://sourceforge.net/projects/lkdump

Please feel free to comment.

Next week, I'll try the following and release new patch.

1) Change codes around add_timer()/del_timer()/etc.
2) Replace dev_t with block_device
3) Clean code more

Another approach is insering some codes into the core timer and tasklet
routines.

For example, 

static inline void add_timer(struct timer_list * timer)
{
	if(crashdump_mode())
		__diskdump_add_timer(timer);
	else
		__mod_timer(timer, timer->expires);
}

But I do not want to make common codes dirty...
Please let me know more good idea!
